The invention relates to a device and to a method for sequestering atmospheric carbon dioxide using at least one air capture module in conjunction with a bioreactor equipped with an autotrophic microorganisms.

The invention features a low cost nature-based carbon sequestering vaccine presenting capacity to restore global Carbon Dioxide to pre-industrial levels over a short, perhaps singly decade use across multiple deployments. This low tech, low cost, high impact, 100% nature based solution is carbon negative during its production and throughout deployment using multiple embodiments that capture and sequestrate carbon dioxide from at least a kiloton approaching a gigaton or beyond scale. The invention uses already developed technologies and biological methods in producing a vaccine for inoculating selected unpopulated or sparsely populated geozones with low potentials for disrupting human activities. Embodiments feature deployment of the vaccine into extreme cold environments with minor or non-existent negative externalities. Extremophilic algal cohorts are selectively adapted by growth in serial culture for spreading at sites where the algae growth and turn carbon dioxide from ambient air into biomass that sequesters the carbon for centuries.

The present disclosure provides a system for processing ultramafic material. The system may comprise a reactor for accelerating weathering of said ultramafic material. The reactor may comprise one or more chambers comprising one or more microbes, biological medicators, or enzymatic accelerants to facilitate the weathering of the ultramafic material.

The invention present provides a method (and suitable apparatus) to convert biomass to ethanol, comprising gasifying the biomass to produce raw syngas; feeding the raw syngas to an acid-gas removal unit to remove at least some CO.sub.2 and produce a conditioned syngas stream; feeding the conditioned syngas stream to a fermentor to biologically convert the syngas to ethanol; capturing a tail gas from an exit of the fermentor, wherein the tail gas comprises at least CO.sub.2 and unconverted CO or H.sub.2; and recycling a first portion of the tail gas to the fermentor and/or a second portion of the tail gas to the acid-gas removal unit. This invention allows for increased syngas conversion to ethanol, improved process efficiency, and better overall biorefinery economics for conversion of biomass to ethanol.

An agent for removing malodor from a painting booth includes a volatile organic compound (VOC) degrading microorganism and a volatile fatty acid (VFA) degrading microorganism. The VOC degrading microorganism is configured to degrade VOC. The VFA degrading microorganism is configured to degrade VFA generated when the VOC is degraded.A method of removing malodor is also disclosed.

An apparatus for removing carbon dioxide from a gas mixture includes at least one artificial leaf. The artificial leaf includes a light transmissive, biodegradable and carbon dioxide and oxygen permeable hydrogel having embedded therein a photosynthetic cyanobacteria capable of the fixing carbon dioxide and a nutrition source for the cyanobacteria. A method of removing carbon dioxide from a gas and a method a making an apparatus for removing carbon dioxide from a gas are also disclosed.

A mobile emissions control system having an emission capturing system and emission control system is provided for diesel engines operated on ocean-going ships at-berth. The emissions control system may be mounted on a towable chassis or mounted on a barge, allowing it to be placed alongside ocean-going ships at-berth. A crane or boom transfers a duct of the emissions capturing system extending from the emissions control system to the ship to capture exhaust from its engine. Alternatively, the system may be mounted on an automated guided vehicle (AGV) equipped with a tower and a crane. The crane mounted on the AGV then lifts the duct forming part of the emissions capture system to the ship's exhaust system to capture exhaust from the ship's diesel engine and transfers it to the emissions control system, which cleans the exhaust and then passes clean air into the atmosphere through an exhaust outlet.

The present disclosure provides compositions and methods for using recombinant C.sub.1 metabolizing microorganisms capable of metabolizing sulfur containing compounds and other contaminants to biologically convert sour or acidic natural gas into high-value molecules, and to allow recovery of stranded oil.

Disclosed is a method of adding a feed medium into a bioprocess. The method includes receiving a stream of CO2-rich gas; treating the stream of CO2-rich gas to remove impurities therefrom; preparing an aqueous mixture for absorbing carbon dioxide, the aqueous mixture having at least one inorganic nitrogen compound in a range of 0.1-50 wt % of the aqueous mixture, the at least one inorganic nitrogen compound is a nitrogen source for microorganisms; absorbing carbon dioxide from the stream of CO2-rich gas into the aqueous mixture, the aqueous mixture with absorbed carbon dioxide forming a feed medium; and adding the feed medium into a bioprocess.
